Title: HYBRID / BATTERY CONTROL: MOTOR GENERATOR CONTROL SYSTEM (for 2WD with NICKEL METAL HYDRIDE BATTERY): P1CB69E; Drive Motor "A" Inverter Voltage Sensor(VH) Stuck On; 2019 - 2020 MY RAV4 HV [11/2018 - 08/2020]

DTC

P1CB69E

Drive Motor "A" Inverter Voltage Sensor(VH) Stuck On

DTC SUMMARY

MALFUNCTION DESCRIPTION

If an overvoltage malfunction occurs in the motor inverter and generator inverter, the motor generator control ECU (MG ECU) detects the malfunction and stores this DTC. The cause of this malfunction may be one of the following:

Internal inverter malfunction

  • Inverter with converter assembly internal circuit malfunction
  • Malfunction in ECU that controls the inverter

CONFIRMATION DRIVING PATTERN

HINT:

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Click here 2019 - 2020 MY RAV4 HV [11/2018 - 08/2020]; HYBRID / BATTERY CONTROL: MOTOR GENERATOR CONTROL SYSTEM (for 2WD with NICKEL METAL HYDRIDE BATTERY): UTILITY

  1. Connect the Techstream to the DLC3.
  2. Turn the power switch on (IG) and turn the Techstream on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the power switch off and wait for 2 minutes or more.
  5. Turn the power switch on (IG) and wait for 5 seconds or more.
  6. Turn the power switch on (READY) and wait for 5 seconds or more.
  7. Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.
  8. Check the DTC judgment result.

    HINT:

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE, perform driving pattern again.

CAUTION / NOTICE / HINT

CAUTION:

  • Before the following operations are conducted, take precautions to prevent electric shock by turning the power switch off, wearing insulated gloves, and removing the service plug grip from HV battery.
    • Inspecting the high-voltage system
    • Disconnecting the low voltage connector of the inverter with converter assembly
    • Disconnecting the low voltage connector of the HV battery
  • To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.
  • After removing the service plug grip from the HV battery, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
  • After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.
